A combination convection and steam oven having a three stage atomizer for breaking up supply water prior to vaporization. The atomizer includes a motor-driven fan having an atomizer cup at its hub which revolves with the fan about an axis of rotation. The atomizer cup has rectilinear or concave walls defining pockets having lengthwise slots at their corners. As the atomizer cup is rotated, supply water is fed into the cup so as to impact the inner surfaces and shear as it exits through the slots under centrifugal force, which directs the water through the fan blades. The supply water thereby is broken up by three separate actions prior to vaporization.

[ What is claimed is:] [1.] An atomizer for use in a combination steam and convection oven for the preparation of food having a heating element and a water line delivering water, the atomizer comprising:a fan rotating about an axis to dispel air radially therefrom and positioned to be surrounded by the heating elements in a path of the dispelled air, the fan having an open face providing access to a fan interior; anda cup attached at the axis to the fan within the fan interior to rotate therewith, the cup having an open face providing access to a cup interior defined by axially extending cup walls receiving the water from the water line, wherein at least one cup wall includes an opening through which the water in the cup interior may pass and the cup walls vary in distance from the axis as a function of an angle about the axis;whereby the cup walls provide impact surfaces striking and atomizing water introduced through the open face of the cup to the cup interior and whereby edges of the opening causes shearing of the water so as to further break up the water passing through the opening before contacting blades of the fan.
